Immediately and 3, 5, 10, and 20 days after the second inoculation, the nasal passages, middle ears, larynges, tracheas, lungs, and salivary and lacrimal glands of four rats from each group were prepared for histologic examination, and the respiratory organs from four other rats were collected for quantitative culture of\n                    <jats:italic toggle=\"yes\">M. pulmonis<\/jats:italic>\n                    and sialodacryoadenitis virus. To test statistically the effect of virus infection on mycoplasmosis lesions, we determined indices of the severity of respiratory tract lesions by subjective scoring. In rats given both organisms, indices of nasal and tracheal lesions were significantly (\n                    <jats:italic toggle=\"yes\">P<\/jats:italic>\n                    &lt; 0.05) greater at 3 days and after than in rats given M. pulmonis alone, and middle ear, laryngeal, and lung lesion indices were significantly greater at 5 days and after. Rats given both mycoplasma and virus had significantly more mycoplasmal colony-forming units in the nasal passages at 3 days and after, and in the larynges, tracheas, and lungs at 10 and 20 days, than rats given only mycoplasma. These results show that sialodacryoadenitis virus infection can exacerbate respiratory mycoplasmosis in rats under experimental conditions; therefore, the virus probably also contributes to expression of naturally occurring mycoplasmosis.\n                  <\/jats:p>","DOI":"10.1177\/030098588702400505","type":"journal-article","created":{"date-parts":[[2017,1,13]],"date-time":"2017-01-13T17:40:24Z","timestamp":1484329224000},"page":"392-399","source":"Crossref","is-referenced-by-count":21,"title":["Exacerbation of Murine Respiratory Mycoplasmosis by Sialodacryoadenitis Virus Infection in Gnotobiotic F344 Rats"],"prefix":"10.1177","volume":"24","author":[{"given":"T.
